Huntington Ravine has LOW avalanche danger. Natural avalanches are very unlikely and human triggered avalanches are unlikely except in isolated pockets. Normal caution is advised.
The ridiculously low temperatures may have abated for the day but the winds have most certainly not. In the last 24 hours winds have averaged 151 kph (94 mph) with a peak gust of 233 kph (145 mph). Today's forecast calls for about the same speeds with temps reaching above -18C (0F). With the windchills as low as they are it will still feel just like the arctic out there.
Some fracture lines are visible in Tuckerman this morning but others have become obscured since the ravine became socked in on Thursday. The high winds have moved snow around and some substantial pockets still exist on strong lee aspects. The areas of most concern are those posted at Moderate today although isolated pockets may exist in those posted at Low. Today's warming temperatures will encourage the settlement of these instabilities that have lingered through the past week's extreme cold. If traveling in avalanche terrain today try and travel on old surface whenever possible. These areas may have been exposed as a result of wind scouring or past avalanche activity.
The John Sherburne ski trail has variable conditions. Expect areas of water ice, new drifts, and abrupt water bars. Be prepared for sudden changes in the trail.
THE LION HEAD WINTER ROUTE IS OPEN. This is a steep and challenging route. Ice axe, crampons, and the skill to use them well are necessary for safe travel. Remember, it is always easier to go up than come down.
AS ALWAYS, THIS ADVISORY IS ONE MORE TOOL TO HELP YOU MAKE YOUR OWN DECISIONS IN AVALANCHE TERRAIN. It should be used along with your own snow stability assessments, knowledge of safe travel techniques, skill in reading mountain weather's effect on the snowpack, and avalanche rescue.
